I respectfully disagree.
200 years of robot-enabled solitude have left House madder than a bag of spanners. A tin-pot despot who only disinguishes himself from Caesar by running up a wholly pointless electricity bill.
The Strip is not pre-war glory, not even close. It's a madman's theme-park.
A madman's theme park? Bah.
I respectfully disagree, as well
Look at it. For some it may be a veritable Sodom. He is not in it for that, however. He is not mad. He is cool, extremely intelligent, and calm. This was the man that singlehandedly saved New Vegas from the war, with excellent foesight, and ran the most powerful robotics corporation the world had ever known.
House's isolation has only left him stronger. He is uncorrupted by the many different lures of the Wasteland, and does not have his mind twisted by glory. He has no interest for it, he simply wants to restore humanity. Vegas' electric bill is his way of saying 'we're open, come on in and pay me money!'
It is a excellent way for him to get his revenue up. With it, he can finance further improvements, and expand his reach far beyond Vegas.
As for the Despotism, democracies have been shown to be corrupted and ineffecient(In the game at least). Already, the NCR is straining over political ineffeciency and a weak government. House solves two problems in one.
1. He controls the Securitrons, but he is not absolutist, he knows that the people are the ones which will propel Vegas into more glory.
2. With everlasting life(or as long as he can keep his electricity on), House can keep a good rule over Vegas for centuries, avoiding that unpleasent anarchy that plagued nations with charismatic leaders who burned out quickly.
3. House has a plan, for all humanity. He will be the one that can finally make man find a new planet, where it can live, without the social boundries of the old world. He can see ahead, and although he is ambitious, he has proof to prop up his claims. He has though every intricate detail so perfectly, that I would trust him much more than the hypocritical soon-to-start-new-great war-NCR, or the Legion, for obvious reasons.
